K5 sensor overheating/on way out?
Does nobody use the Eyepiece M designed for the purpose? It's also worth noting that if we use the 2 second delayed action, not only is the mirror locked up before exposure (reducung vibration) but also the exposure is locked, so at that point we can take our eye away from the viewfinder.

K5 sensor overheating/on way out?
I understand, perhaps I don't experience this as a problem because I'm still stood behind the camera, so it's in shadow anyway. On the face of it, to have so long and exposure in light bright enough to cause a problem, seems like quite an extreme situation, so is this happening when very dark ND ...

K5 sensor overheating/on way out?
I've just been back & read the whole thread (usually a good idea before commenting) The problem occurs with a Cokin ND110, and appears to be still present (but improved) with the eyepiece covered. One other possibilty is light getting on the back of the Cokin filter. Their filter holders are not i...

K5 sensor overheating/on way out?
Yes this thread is about the 10stop ND. I use the screw-in B&W, so all the light leakeage is viewfinder. Of the squares I know the Lee has a foam seal and I'd like one eventually as the blue cast seems easier to deal with than the B&W purple. But they seem just about impossible to find, they seem...

K5 sensor overheating/on way out?
Unfortunately I missed this thread, I could have diagnosed that immediately. One of my useful photo accessories is a lump of blue tac to stick over the viewfinder to prevent this light leakage with long exposures. LOL - I use the same thing.

K5 sensor overheating/on way out?
BluTac causes smears on the eypiece. I use a small rectangular piece of black plastic, cut from a tape casette box, 33x22mm with the corners rounded. This tucks under the rubber surround. The official one is IMO a complete pain as it requires the rubber surround to be removed, which invariabl...

K5 sensor overheating/on way out?
That's an idea. I've never got the blu tac mear on the eyepiece, but it does leave residue on the rubber surround. I'm thinking of switching to a piece of black electrical tape attached to the flash cover.

I use the anti-smear blutac, which is red.

K5 sensor overheating/on way out?
Thanks for resurrecting this topic...it's reinforced my assumptions after trying out my own '10-stop ND' filter for the first time, about 3 weeks ago. This was one of the best of a bad bunch! The sun was quite strong and coming in from the right hand side. Right...now where did I put tha...

K5 sensor overheating/on way out?
I think this is almost 100% definitely light leakage, either via the eyepiece or at the filter end. I have experienced the same issues taking Infra-red shots with my K-x and a screw on Hoya filter, but only in certain lighting ocnditions which re-inforces the fact that it is leakage of light. I su...

K5 sensor overheating/on way out?
I had exactly that same effect when I used a welding glass blu-tacked to a filter ring. Two things cured it :- A black electricians tape around the edges of the glass B Blacking out the eyepiece (see my previous comment) regards Bernard

K5 sensor overheating/on way out?
Mmmm, I have had a similar problem using Lee 10stop filters. Then I fitted the viewfinder cap and it all went away. Also streaking caused by poor sensor cleaning. As has been suggested try a 'wet'clean. I have only had the K5's for a few months but I have had exposures of three, four and almost...

A couple of points: black velevet scrunchies that girls tie their hair back with are exactly the right size to fit around a lens barrel and block out reflected light on Cokin and similar filter systems. Get down to your local branch of Accessorize with 90p in your hand. Light entering the viewfin...

K5 sensor overheating/on way out?
Interesting thread, proves that having a eyecap cover really does work. Now I am thinking, for landscape use, there is one solution albeit pricy over an eyecap or scruntchie, In fact it could be this thing's USP. The K-01! Told it was not a cheap option, but in fact, could be a very useful on...

Sensor Clean (wet)
I should be grateful for recommendations. I noticed some blobs on my K5 sensor. They have proved hard to shift. I tried the camera sensor clean (no difference) then a blower (no difference) then Arctic butterfly (made it worse, arrrgh). So I think I'll have to resort to a wet clean. I've googled...

Sensor Clean (wet)
Your camera model will influence your decision. Some of the older Pentax bodies could use Eclipse fluid. Newer ones require Eclipse 2 because of the coatings on the low-pass filter (the bit you actually clean). I've never had any muck on mine that couldn't be shifted by the Arctic Butterfly so I ...

Visible Dust (maker of the Butterfly) also has a wet cleaning option. SRS stock it. Do Pentax still make their sensor cleaning kit?
